SHOW-WINDOW VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 331,077, dated November24, 1885.

Application filed June 21, 1883. Renewed October 10, 1885. Serial No. 179,532. (No model.)

To all whom it may concern.-

Beit known that we, MARTIN G. Mooi; and WALTER S. MAYwooD, citizens of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented a new and useful Improvement in ShowWin dow Ventilators, of which the following is a specification.

Our invention relates to improvements in show-window ventilators; and the objects of our improvements are to provide a cheap and simple method and apparatus for Ventilating inclosed windows. Ve attain these objects by the mechanism illustrated by the accompanying drawings, in which- Figure l is a perspective view of our invention with a part broken away. Fig. 2is a vertical section of the same, and Fig. 3 is a view looking down on the bottom of our invention.

Similar letters refer to similar parts throughout the several views.

Ourinvention consists in providing air-lues at the bottom of a window, with a hinged lid over the upper end of the same, operated bya cord or wire, and making suitable openings at the top of the said window.

On the drawings, A represents the frame of the window, B the end glass, and B the front glass. The tlues a are attached at theirupper ends to the tloor c, and hang perpendicular near the sides of the frame A, as shown in Figs. l and 2. The said tlues a are made of wood or iron, or partly of each, being curved outward at the bottom, so as to catch the inward current of air more freely, all as shown in Figs. 1 and 2. In windows that are not pro* vided with open or grated fronts D the lower end of the tlue a is passed through and securedl to the front, as shown at a in Fig. l. The lids b are hinged around the outer edge of the bottom c by hinges b', and they are connected together by staples t' t at their ends, as shown in Fig. 3, so that when one is raised it raises the other accordingly. A cord or wire, e, is attached to one of the lids, and passes up over the hooks e', then down sufficiently to be easily reached to operate the lids at will. A false bottom, c, is placed on the bottom c", resting on the bars c', so that goods may be placed on the said bottom c wit-hout interfering with the Ventilating mechanism. The air drawsin through the dues t ct, passes up along the glass and out at the openings f, thus making the air inside the window uniform in temperature with that outside, preventing the accumulation of frost or sweat on the said glass.

In warm or dusty weather the lids may be let down, if desired.

Having thus described our invention, we claim the following and desire tosecure the same by Letters Patent:

The hinged lids b and the staples i, which connect them, in order that all of said lids may be raised and lowered together, in combination with the cord e, attached to one of said lids, the bottom c, false bottom c2, and showcase having inlet-dues a at the bottom and outlet-dues f at the top, substantially as set forth.
